1. General
Congratulations on your new explosion-safe AR-051 air conditioner. If you follow the
instructions in this user manual, your new air conditioner will give you years of enjoyment.
The explosion-safe AR-051 air conditioner has been designed to safely provide users with
cool and warm air in order to maintain the desired room temperature.
The air conditioning system consists of an outdoor unit and an indoor unit with remote
control. In function the system refrigerates air. The indoor unit contains a heat exchanger
which is connected to the outdoor unit using special tubing. The outdoor unit provides a
continuous flow of cold fluid which decreases the temperature of the heat exchanger, which
in its turn absorbs the energy of the air, resulting in a room air temperature decrease. The
remote control enables the user to operate the indoor unit.
The outdoor unit consists of a sheet steel enclosure and contains a heat exchanger, a
hermetically sealed compressor, one on more valves for controlling the refrigerant, an
electrically driven fan assembly, electronics PCB and NTC temperature sensors. The sheet
steel enclosure is partly part of the protection degree against ignition applied.
The indoor unit consists of a heat exchanger, an electrically driven fan assembly, electronics
PCB and NTC temperature sensors all covered by a non-metallic hood. The infra-red remote
control contains electronics with a display and membrane pushbuttons all housed in a non-
metallic housing containing two 1,5 V DC AAA dry cell batteries. Alternatively, a wired remote

control for fixed mounting against the wall can be supplied. Power to the wired remote control
is provided by the indoor unit.
From explosion safety perspective, the ambient temperature allowed for the apparatus is
-27 °C up to +52 °C. This range might be restricted due to the operational limits of the unit.
The AR-051 air conditioners have a CE label and comply with the European EMC and ATEX
directives and therefore implicitly comply with the European Low Voltage Directive.
